September's Half Price Book

I do love a locked room mystery. You know the kind of thing – a body is found in the library, dastardly doings have occurred, but the door is locked from the inside with no visible means of entry or, indeed, exit for the perpetrator. This collection features lesser known stories from some big names (the Conan Doyle is a special treat) and some undiscovered gems from people you won’t ever have heard of. My favourite was The Invisible Weapon. Go on…challenge yourself!
